SIMULATION OF THE RESIN FLOW PROCESS OF THE COMPOSITE K/T TYPED JOINTS USING VACUUM ASSISTED RESIN TRANSFER MOLDING

Abstract

Abstract: The large-span structure has obtained a rapid development during the advance of urbanization, which requires pipeline structures with good mechanical properties and corrosion resistance. The conventional pipe part is composing of metal concrete structure, which has the disadvantages in the wet and corrosive cases. The composites have widely regarded as the promising materials in civil engineering design for the high specific strength and corrosion resistance, which has greatly hindered the application in the fields of cost control. In this study, the composite K/T typed joints were obtained using the vacuum assisted resin transfer molding (VARTM) process and the suitable resin injection method was determined based on the simulation results of resin flow front shape and injection time for the four injection methods, which was compared with the testing result with the determined injection method. Both of these results present good agreement with each other, which can avoid the high cost of the trial and error method.

Key words: composite, K/T typed joints, VARTM process, resin flow, simulation
